El Diente Peak, Mountain summit in San Juan Mountains, Colorado, US

El Diente Peak is a summit in the San Juan Mountains that rises to approximately 14,165 feet and features a tooth-shaped profile visible from across the range. The terrain consists of rocky slopes, sharp ridges, and talus fields that make the ascent technically demanding.

The name El Diente, Spanish for "The Tooth", comes from the peak's pointed profile. Its topographic prominence is only 239 feet (73 m), below the 300-foot cutoff, but the 3/4-mile connecting ridge to Mount Wilson is Class 4/5 terrain, so it is often counted as a full fourteener. The sources record no first-ascent date or climbers.

The name is Spanish for "The Tooth", referring to the peak's pointed profile. The summit lies in the Lizard Head Wilderness of San Juan National Forest, 10.5 miles north by east of Rico in Dolores County. The connecting ridge to Mount Wilson is a Class 4/5 climb over 3/4 mile.

Climbers access the mountain through two main trailheads: Kilpacker Trailhead starting around 10,060 feet (3,070 m) or Woods Lake Trailhead starting around 9,352 feet (2,850 m). Navajo Lake provides camping options for those planning a longer visit.

El Diente's prominence is only 239 feet (73 m), so a strict 300-foot rule would not count it as separate from Mount Wilson. The 3/4-mile connecting ridge is Class 4/5, which is why climbers treat it as a full fourteener. In 2019 a climber survived a 600-foot fall into an avalanche chute and was airlifted after activating a GPS emergency signal.
